VALVED HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 325,720, datedSeptember 8, 1885.

(No mcdel.)

To @ZZ whom it may concern.-

Be it known that I, JOHN AsHwoRTH, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Valved Hose-Nozzles, of whichthe following is a specitieation.

This invention relates tothe valvular parts of hose-nozzles, moreespecially such as are used in i'e extinguishing apparatus. Asheretofore constructed these nozzles have been provided usually withplug-valves, which afford no way of changing the size of the streamother than by contracting the water -way through the partial rotation ofthe plug. This, however, destroys the solid character of the stream andmaterially detracts from its carrying ability. Moreover, if theplug-valved nozzle freezes, as it is very apt to do in cold weather whenthe valve is closed, it often happens that the nozzle is ruined throughthe expansion of the plug-chamber caused by the solidifying of thecontained water. The plugvalve requires also to be closely fitted in itschamber, and the wearing away through friction of the parts sooner orlater destroys this fit and renders the valve leaky.

To obviate the damage through freezing, lessen the evil caused byfriction, and provide for the throwing of a small unbroken stream arethe objects had in View in the present invention. I substitute for theplug and other valves heretofore used a gate or transverselyslidingvalve, aftiXing to the nozzle a lateral chamber into which such valveismoved when the water-way is opened, and operate it by means of a pinionmeshing with a rack upon the valve. The pressure of the Water keeps thisvalve tightly to its seat at all times when closed, and as both it andits seat are straight parallel surfaces whatever wear may occur is atonce taken up by the pressure, so that no leakage is likely to occurfrom that cause. If

this valve freezes when closed,there is no plugchamber to be expanded.XVhile, of course, this form of valve admits of the throwing of apartial stream by being partially opened, as does the plug-valve, yetsuch partial opening does not always produce the desired kind of stream,andv I therefore provide the valve with a central opening, which isitself closed by au independent valve borne upon the main valve. Thissupplemental valve I make in the form of a slide upon the main valve,and it is operated by the same pinion by which the main valve is openedand closed, the rack before mentioned being forinrd upon it. The openingin the valve being thus centrally located, permits a small stream ofwater to issue into the center of the bore of the nozzle-tip and to passthrough the latter without contact with it.

All these features of the invention are more fully set forth below, andwill be understood by reference to the accompanying drawings, in which-Figure lis a side view of the nozzle embodying my present invention.Fig. 2 is a transverse or rear end view. Fig. 3 is a eentrallongitudinal section showing the valve open. Fig. 4L is a similar View,showing the 7o valve closed, and Fig. 5 is a horizontal section uponline 5 5 of Fig. 3.

Insaid drawings, A represents the tip of the nozzle,and A the butt, aportion of the latter only being shown. Between these parts I insert thevalve-holding part B. Within this part B is the transversely-slidinggate-valve C, the walls of the water-way being slotted to receive thevalve and to furnish it with a seat, c. B is, a lateral chamber upon thepart B, into which the valve is moved when opened, and within this samechamber is located a pinion, C', for operating the valve. One end of thejournal of this pinion projects to the outside, and is there providedwith a handle, C2. The top of the' chamber B is closed by a removablecap, b. The valve is provided with a rack, with which the pinion meshes,so that by turning the handle the valve may be moved in or out, asrequired. It will be noticed that 9o the pressure of the water upon thebutt side of the valve will keep it rmly against the seat c, therebypreventing leakage; also, that any wear upon the valve or its seat is atonce taken up by the pressing action of the water, 95 and that expansionthrough freezing is not likely to affect in any way the tightness of thecontact between those parts.

For the purpose oi" throwing a small but solid stream, an opening, d, ismade in the valve,and is so located therein as to occupy a centralposition in the water-way when the valve is closed. This is to enablethe stream to pass out through the tip without contact with it, whichmight affect its solidity or direction. This opening is co-ntrolled by asliding piece, D, held to the valve by dovetailing, as shown in Fig. 5,or insonie otherequivalent manner, and provided with an opening, d',which may be made to register with the opening d inthe valve when thesmall stream is to be thrown. The 'rack before mentioned I prefer toform upon this sliding piece, as it enables the operating ot' both themain valve and the slide by a single pinion, the slide being providedwith a pin, d", which engages with the ends of the slot d3 in the mainvalve, as clearly illustrated. NVith this construction, when it isdesired to use the small stream the parts are iirst moved into theclosed position and then the movement of the pinion is reversed untilythe slide is raised sutliciently to bring the opening d in register withthe opening d. It ismanifest that this supplemental 'valve may beotherwise secured and otherwise operated, and hence I do not wish to belimited to the exact construction shown; but I have illustrated thebestand simplest construction known to me; In the bottom of the sectionB a set-screw, e, may be employed, as shown in Figs. 3 and 4, toregulate theposition ot' the main valve when closed. The section 13,1prefer to make separate from the tip and butt, to which it may beconnected by the usual screw-joints, as more convenient in manufacturingand as admitting changes of this part When damaged without the necessityof replacing t-he other parts. It may, however,

be cast in one piece with the tip or butt, or

for closing such opening, substantially asV- specified.

2. The hose-nozzle provided with and closed by a gatewalve provided Witha small streamopening and carrying a rack-faced pierced valve adapted toregister with said opening, andasingle pinion for operating both valves,substantially as specified.

3. As a new manufacture, the hose-nozzle having the two sliding valves,one for shutting off the full stream and the other the\ small stream,and both operating in the bore 0f the nozzle, substantially asspecified.

4. rIhe combination, in a hose-nozzle, of the main valve, therack-carrying slide-valve secured substantially as described to the mainvalve, and the operating pinion meshing with said rack, essentially asset forth.

5I The hose-,nozzle having two slide or gate valves, one adapted to shutoff the full stream and the other'to shut off the small stream, thelatter valve being mounted upon the former, substantially as specified.

6. The combination, in a hose-nozzle, of the gate-valve having a smallstream -opening, the rack and pinion for moving said valve, and thescrew e for positioning the valve when closed, whereby the smallstreambpening is caused to occupy the center of the water-way,substantially as specitied.
